5. Evaluating the Performance of Propulsion System Elements in an Aerospace Company
University essay from KTH/Kraft- och värmeteknologiAbstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions. READ MORE
